I think a pretty good example of how to describe what you do on your site is http://verily.com (owned by Alphabet/Google).

'We create tools that put health data into action' hits you right in the face when you visit the page. Then you scroll down and see good descriptions of their products.

As someone who visited their site after looking through similar sites filled with marketing crap, I found it a relief to see something so simple. Use this as a startup website template instead!
